RE: How to determine a widget is visible or not within a scrollw?

[martyn 2 russell bt com]

I know this might not be the best way to do it, but you might be able to do
the following

1. set up a event handler for grab_focus on the widgets inside the layout.
2. on the event, check to see if it is exposed, if not, move the scrolled
window down (the question is - how much).

Just a thought...

Martyn
